A scanner includes a first illuminant device having a first power associated therewith, and a second illuminant device having a second power associated therewith. The first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document. The scanner is configured to select one of the first illuminant device and the second illuminant device based, at least in part on, a level of power supplied to the scanner via a power source, and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A scanner comprising: a first illuminant device having a first power associated therewith; and a second illuminant device having a second power associated therewith, wherein the first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document, wherein the scanner is configured to: select one of the first illuminant device and the second illuminant device based, at least in part, on a level of power supplied to the scanner via a power source; and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
2. The scanner of claim 1 , wherein the scanner is further configured to adjust a scan speed based on the selected one of the first illuminant device and the second illuminant device.
3. The scanner of claim 1 , wherein the scanner is further configured to detect the level of power supplied to the scanner, wherein the first illuminant device is selected responsive to detection of the first power, and wherein the second illuminant device is selected responsive to detection of the second power.
4. The scanner of claim 1 , wherein the first power comprises an urban power source.
5. The scanner of claim 1 , wherein the second power comprises power provided by a computer connected to the scanner.
6. The scanner of claim 1 , wherein the first illuminant device consumes more power per scan than the second illuminant device.
7. The scanner of claim 1 , wherein each of the first illuminant device and the second illuminant device is configured to scan a same side of the document.
8. A method, comprising: detecting a level of power supplied to a scanner, wherein a first level of power is associated with a first illuminant device, and wherein a second level of power is associated with a second illuminant device, each of the first illuminant device and the second illuminant device is configured to selectively scan a document; selecting one of the first illuminant device and the second illuminant device based, at least in part, on the level of power supplied to the scanner; and performing a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
9. The method of claim 8 , further comprising adjusting a scan speed of the scanner based on the selected one of the first illuminant device and the second illuminant device.
10. The method of claim 8 , wherein the first illuminant device is selected in response to detection of the first level of power, and wherein the second illuminant device is selected in response to detection of the second level of power.
11. The method of claim 8 , wherein the first level of power is provided by an urban power source.
12. The method of claim 8 , wherein the second level of power comprises bus power of a computer.
13. The method of claim 12 , wherein the scanner is connected to the computer.
14. The method of claim 8 , wherein the first illuminant device produces a relatively higher level of brightness in performing the single scan compared to the second illuminant device.
15. An apparatus, comprising: means for determining a level of power supplied to a scanner, wherein a first level of power is associated with a first illuminant setting, and wherein a second level of power is associated with a second illuminant setting, each of the first illuminant setting and the second illuminant setting for selectively scanning a document; means for selecting one of the first illuminant setting and the second illuminant setting based, at least in part, on the level of power supplied to the scanner; and means for performing a single scan of the document using only the selected one of the first illuminant setting and the second illuminant setting.
16. The apparatus of claim 15 , further comprising means for adjusting a scan speed of the scanner based on the selected one of the first illuminant setting and the second illuminant setting.
17. The apparatus of claim 16 , wherein the scan speed associated with the second illuminant setting is greater than the scan speed associated with the first illuminant setting.
18. The apparatus of claim 15 , further comprising means for adjusting a scan speed of the scanner based on the determined one of the first level of power and the second level of power.
19. The apparatus of claim 15 , wherein the scanner is configured to scan a same side of the document using either the first illuminant setting or the second illuminant setting.
20. The apparatus of claim 15 , wherein the first illuminant setting is selected responsive to the second level of power being disconnected.
